Further Information on File Contents


Each of the SIH 2011-12 Basic and Expanded CURFs contain the following record levels:

    • Household level – contains information such as state or territory and area (capital city/balance of state) of residence, housing characteristics (including tenure and housing costs), dwelling characteristics, household type and composition, household income by broad level source of income, household wealth, imputed rent, demographic information, and some information relating to the household reference person.
    • Income unit level – contains information such as income by broad level source of income, weekly rent payments, income unit type, selected housing characteristics (including tenure type and landlord type), child care use and costs, and demographic information.
    • Person level – contains information about age, sex, marital status, relationship in household, country of birth, year of arrival in Australia, family type, income unit type, labour force details, occupation and industry, education status, education qualifications and education institution attending, income by detailed source of income, barriers to labour force participation due to child care related reasons, and some information on personal assets. Person records exist only for persons aged 15 and over.
    • Loans level – contains information about the characteristics of each loan, such as the main purpose, security, amount borrowed, principal outstanding and weekly repayment.
The first three levels are in a hierarchical relationship: a person is a member of an income unit, which is a member of a household. Level four is in a hierarchical relationship with the household level.

There are several identifiers on records at each level of the file. There are also weights on records at each level of the file to enable the production of estimates for the whole population.

A complete list of the data items available on each record level for the CURFs is available from the Downloads tab.
